About Us

^{DELLOK (YONGHUI RADIATING PIPE MANUFACTURING CO.,LTD.) was established in 2002, which is located in Jiangsu, China. After many years of development, the company now has 66 million yuan in fixed assets, more than 200 employees, and 33 technical staffs. We have 4 aluminum processing production lines, with the annual processing capacity of more than 20,000 tons; And we have 5 tube-drawing production lines; 47 fintube production lines, 1 imported production line from American with the brand of McElroy , with the annual production capacity of 12 million meters the above. Quality is the theme of eternal pursuit of winner -Production workshop- Meticulous works, standardized management system and systematic quality assurance are Dellok(YONGHUI)'s best commitment to quality. In Dellok(YONGHUI), the quality control is not only the detection of the final process, but throughout the entire production process. We implement a set of quality control and assurance systems. Each batch of pipes is sampled and tested, and records are kept as a quality guarantee for the final product.}

Laser Welded Finned Tube Product Description:

^{Laser welded Fin Tube features high heat transfer efficiency, and strong welding seam.}

^{It allow to be made with different fin shape.}

^{These fin tubes can be used on condensing heating system.}

^{The complete connection between the fins and the base tube brings about excellent heat transfer and up to 2.5 times higher thermal performance of the finned tubes.}

^{The continuous weld prevents notch effects and corrosion and the formation of cracks are hence avoided also in the case of possibly oscillating finned tubes.}

^{The low base metal heating during welding and the high speed of travel of up to 20m/min. minimize the heat-affected zone in the base tube. Complete melting of the tube and a related metallurgical transformation of the parent metals are hence excluded.}

Laser Welding Fin Tube Manufacturing Process:

^{The fin strip is welded continuously and spirally wound onto a polished bare tube. And the tube and fins are bonded together by using advanced laser welding technique.}
